That's a very small space with a whole lot of PA. The subs will give you some feel, but since you need some space behind the subs to make cardioid work regardless of which box(es) you choose, you're talking...25' or so of coverage? Who is going to benefit from the rear cancellation lobe, anyone?You mention "studio" - if this is just a rehearsal space and you're already on a tight budget, skip the cardioid for now. Just do a single sub that plays nice with your system — so another JBL SRX 800 series, just for some last-octave feel — and call it a day. Then if you need subs for any future outdoor gigs, rent them on an as-needed basis.
